Conservation and Restoration

5 ECTS; 2º Ano, 1º Semestre, 15,0 T + 60,0 PL + 3,0 OT

Lecturer
- Fernando dos Santos Antunes

Prerequisites
Not applicable.

Objectives
-To know the main international and Portuguese aesthetic-artistic styles and trends of retables or altarpieces and woodcarving production.
-Identify the materials, techniques and technologies of the production of the objects.
-Understand and relate the cultural characteristics of the object: artistic and aesthetic; iconographic and iconological; functional and sociological.
-To evaluate the state of conservation of the object and to diagnose, taking into account the factors of deterioration, the previous interventions, its environmental and historical context.
-Identify and understand the alterability and alteration of the object: natural aging of the materials; and the alteration - damages and pathologies.
-Formulate, justify and apply intervention methodologies taking into account the ethical principles of conservation and restoration.
-Know and understand the main procedures - materials and techniques - for the conservation and restoration of retables or altarpieces and woodcarvings.

Evaluation Methodology
Acts of Integrated Evaluation and Their Weighting in Continuous and Final Evaluation:

Theoretical(50%)
-Technical Report Form + Work Sheet(25%)
-Written Work(25%)

Laboratory Practice (50%)
-Performance(35%)
-Attendance(15%)

Additional information:
-The students are obliged to comply with all assessment items, being able to choose to be globally assessed in continuous assessment, or in final assessment;
-The students, to be admitted to the final evaluation, must have a positive evaluation of the laboratory practical component, with a minimum of 9.5 values, in continuous evaluation;
-the students will be able to submit the written works of the theoretical component in final evaluation - exam period;
-Eventual improvements will be made only to the theoretical component - written works - being considered in the final global weighting the evaluation obtained in the laboratory practical component.
